Katy Perry's next album won't all be about her heartbreak following her divorce from Russell Brand

It has been speculated the 'Part of Me' singer's third album will be about her upset in the wake of her divorce from comedian Russell Brand, but she has promised there will be an upbeat side to it as well.

She told The Sun newspaper: "I'd never devote a whole record to heartbreak. I'm happy, I'm in a good place, I'm looking forward to my future."

Katy - who split from Russell in December after 14 months of marriage - also spoke about scenes in the movie when her marriage was in trouble, and why she included them in the film.

She added: "For me it was important with this movie not to ignore that elephant in the room.

"I am not hiding anything, but I had to put it in with integrity and consideration because that's how I make all my choices, because I believe in karma."

Speaking of scenes in Brazil where she is crying before going on stage, the 27-year-old added: "That's toward the end of the tour and I am obviously exhausted and things aren't going well for me personally. I am trying to keep that to myself and it started cracking through.

"It is a bit of a symbolic moment, rising above that pain on that lift [to the stage], and sometimes I had to turn it on. I turned on my spinning outfits and my spinning peppermints."

Katy is now believed to be dating Florence + the Machine guitarist Robert Ackroyd, but she has said their relationship is not serious.
